Abstract
Description
- This application is a continuation-in-part of my co-pending application Ser. No. 10/797,896 filed on Mar. 10, 2004, entitled “Duct Holder,” the full disclosure of which is incorporated by reference herein, and priority of which is hereby claimed.
- The present invention relates to conduit supports and, more particularly, to a support or holder for supporting hollow conduits, such as air, heating ducts or pipes between adjacent joists of a building structure.
- Conventionally, heating, cooling, ventilating and air conditioning systems (HVAC systems) in buildings use pipes, tubes, flexible ducts and other tubular bodies for conveying the air within the building. The tubular conduits are supported between floor or ceiling joists and normally secured in a suspended position by nylon straps or metal hangers that are placed between the joists. One problem with conventional duct supports is that the nylon straps or metal brackets have to be secured to a rafter, which in some cases is located at a relatively high level above a base surface, or floor of an attic. To reach the rafter, the worker has to climb a ladder or construct a special platform high enough to give access to the rafter. Naturally, such method of suspending the tubular conduits takes time and increases the cost of the labor involved in the construction of the building.
- Another problem with the use of flexible straps is that they tend to constrict the airflow within a flexible duct. When the strap is tied to the rafter, it is estimated that about 25% of airflow may be lost due to the duct constriction. Still another problem associated with suspending the air ducts is that a condensate tends to form in the portion of the air duct that sagged between adjacent straps. The accumulated moisture drips into the insulation, where it can cause damage or facilitate development of mold and mildew around the duct.
- The present invention contemplates elimination of drawbacks associated with conventional methods and provision of a duct support that can support the ducts or other tubular conduits from above or below the conduit without constricting the flow of gas or fluid through the conduit.
- It is therefore, an object of the present invention to provide a duct support that can be used in place of conventional conduit supports in a building.
- It is another object of the present invention to provide a duct support particularly adapted for use with air circulation systems wherein the conduits have to be supported at certain intervals along their lengths.
- It is a further object of the present invention to provide an air duct support that can be secured to either a joist or rafter and effectively support the air duct without constricting the air flow through the air duct.
- These and other objects of the present invention are achieved through a provision of a support device that allows the conduit to be elevated above a base surface, such as the attic floor, without constricting the air flow passing through the conduit. The support device has an arcuate main body and an upright support member, to which the main body is engaged in free rotational relationship. The main body defines an open channel for receiving a portion of a conduit therein. The channel is sized and shaped to accommodate different shape and diameter conduit, such as for instance air ducts. The upright support can be formed as an upright planar member or with a pair of spaced legs and allow positioning of the conduit at a desired height above a base surface.
- To prevent displacement of the conduit, especially if the support device is mounted to a rafter and suspends the main body below the support member, is provided with a collar plate or a strap that wraps about an unsupported portion of the air duct. The device can be also secured to joists, allowing the main body to be oriented above the support member.

support member 14 is formed as a unitary body. A pair ofcuts walls FIG. 35 ). Anattachment bridge 40 is formed by the uppermost part of thesupport member 14. Theattachment bridge 40 comprises acentral portion 42, which has the same width as thecentral wall 22, and a pair ofside tabs 34, 36, which have the same widths as theside walls - When the
attachment bridge 40 is prepared for securing to themain body 12, thebridge 40 is bent at 90 degrees in relation to thecentral wall 22. Acentral opening 48 made in theattachment bridge 40 receives therivet 36, allowing themain body 12 to freely rotate in relation to theupright support 14. Anopening 50 is formed in aside tab 44, and a similar opening 52 is formed in theside tab 46. - When preparing the
support 10 for installation, first moves themain body 12 to orient themain body 12 above the support 14 (FIGS. 28 a-28 c). Themain body 12 may be pivotally or hingedly attached to thesupport member 14, as shown inFIGS. 28 a-28 c. The user then bends down thebridge 40 and then theside tabs 44 and/or 46 (FIGS. 28 d and 28 e) at 90 degrees, so that theside tabs side walls rivet 36 is inserted through the opening made in themain body 12 and through theopening 48. - An
opening 54 is made in thewall 24 and asimilar opening 56 is made in thewall 26. A user aligns theopening 50 with theopening 54 in thewall 24, and/or aligns the opening 52 with theopening 56 in thewall 26. A user then inserts a retaining device, such as for instance a screw 58 (FIG. 28f ) through the alignedopenings 52, 56. An optional second retaining device may be inserted through theopenings support 14 is thereby made more stable and rigid. - If necessary, an optional
support extension member 60 can be added to extend the height of theupright member 14. Theextension member 60 has the same U-shaped configuration as thesupport member 14, but smaller in size, so that theextension member 60 fits within the channel defined by thecentral wall 22 and theside walls FIGS. 11 and 12 , theextension member 60 has a central wall 62 and a pair of opposingparallel side walls 64, 66 (FIGS. 11 and 12 ). - The central wall 62 is provided with a plurality of spaced openings 68 that are aligned in a manner similar to the
openings 28 in thecentral wall 22. When the height extension of theupright support 14 is desired, theextension member 60 is fitted in the channel formed by thecentral wall 22 and theside walls FIG. 29 ), and a retaining device, a screw, bolt, etc., is inserted through the alignedopenings 28, 68. - Turning now to
FIG. 13-15 , acollar plate 70 for use with the air duct support device of the present can be seen in more detail. Thecollar plate 70 comprises a planar body having a generally rectangular configuration with opposingparallel edges Edges edges elongated slot 80 is formed adjacent theedge 72, and anelongated slot 82 is formed adjacent theedge 74. Theslots - A pair of opposing
notches edge edge 72, and a similar pair of opposingnotches 88, 90 is formed in theedges edge 74. Thenotches collar plate 70 for engagement with themain body 12. A plurality of spacednotches 92 is formed along theedge 76 between thenotches notches 94 is formed in theedge 78 between thenotches 86, 90. - Turning now to
FIGS. 31 a and 31 b, a process of preparing thecollar 70 for use is shown in more detail. The user bends theedges side tabs FIGS. 31 a and 31 b. After aconduit 11 is positioned in thechannel 16, the user inserts thetabs 96, 98 in opposingslots 20 adjacent anend 15 of themain body 12. This step is schematically illustrated inFIG. 32 a. The user then brings thecollar 70 around theconduit 11 and secures thetabs slots 20 near theend 17 of themain body 12. - Should the
collar 70 be too long, the user follows the steps schematically illustrated inFIGS. 32 b and 32 c: the user cuts thecollar 70 along an imaginary line extending between thenotches collar 70 to the outside dimensions of theconduit 11. The excess length of thecollar 70 is discarded,new side tabs notches 20 adjacent theend 17. - The collar plate can be formed from a variety of materials, such as thin aluminum plate, thin steel plate and the like. The preferred material can be bended without breaking, is non-corrosive and strong enough to support the weight of the air duct in applications where the
main body 12 is below thesupport member 14, such as when thedevice 10 is secured to a rafter (FIG. 33 ). - Some tests performed with the prototype of the present invention showed that the
conduit 11 can vibrate and “rattle” when a strong air flow passes through theduct 11. To cure the problem, the instant invention provides for the use of aflexible strap 110, which is wrapped around the exposed portion of the conduit positioned in thechannel 16. Thestrap 110 is shown is detail inFIGS. 16-22 . Thestrap 110 comprises an elongatedflexible body 112 having aninner surface 114, anouter surface 116, and opposing ends 118, 120. Theflexible body 112 may be made from a stretchable, resilient material. - The strap end 118 is folded over to form an open fold 122, and the
strap end 120 is folded over to form anopen fold 124. A hook member 126 is secured in the fold 122, and ahook member 128 is positioned in thefold 124. Thehook members 126 and 128 are identical; both have ahook portion 130 and anattachment part 132, which is configured as a rectangular frame with anopening 134. The strap ends 118, 120 are threaded through theopening 134 before folding over. The free ends of thestrap 136, 138 are secured to the main body of thestrap 112 by stitching, adhesive or any other suitable means. - In operation, the user engages the
hook 130 in one of theopenings 27 and wraps thestrap 110 around theduct 11, as shown inFIGS. 23-25 . The user then secures the opposite end of the strap to the other side of themain body 12 by engaging thesecond hook 130 with the opening on the other side of themain body 12. Thesupport device 10 can be used in an upright position, with themain body 12 being above thesupport member 14, as shown inFIG. 34 , or suspended from a rafter, as shown inFIG. 33 . - When suspended from a
rafter 140, themain body 12 has thechannel 16 open downwardly. In this application, thecollar plate 70 or thestrap 110 are preferably used to prevent theconduit 11 from slipping out of themain body 12. Thesupport member 14 is secured to the rafter by screws, nails, or other suitable means. When extended upward from a joist, themain body 12 is positioned above thesupport member 14 and the opening of thechannel 16 is oriented upwardly. Theconduit 11 rests within thechannel 16 without any assistance from acollar 70 or thestrap 110. Still, thestrap 110 may be used to reduce vibration, if desired. Where needed, thesupport units 10 may be used at about 4-5 feet intervals. - The second embodiment of the air duct support device of the present invention is shown in
FIGS. 6-10 and 26-27. The second embodiment is generally designated bynumeral 150. The airduct support device 150 comprises amain body 152 and asupport member 154. Themain body 152, similarly to the first embodiment, comprises an arcuate body defining anopen channel 156 having an opening between opposing ends 153, 155. Themain body 152 is provided with two parallel rows of spacedelongated notches openings 161 made between the rows ofnotches notches collar plate 70, while theopenings 161 are adapted to receivehooks 130 when thestrap 110 is used. - The
support member 154, in this embodiment, comprises a pair of spread-apart legs main body 152. Thelegs bridge plate 166, which is secured to themain body 152 by arivet 168. Therivet 168 allows free rotation of themain body 152 in relation to thesupport legs main body 12 in relation to theupright support member 14. In both embodiments, themain body conduit 11. - The
leg 162 comprises anelongated support plate 163 and a unitary formedattachment plate 165 extending at an obtuse angle in relation to the longitudinal axis of thesupport plate 163. Theleg 164 comprises anelongated support plate 167 and aunitary attachment plate 169 secured at an obtuse angle to a longitudinal axis of thesupport plate 167. Anopening 170 is formed in theattachment plate 165, and an opening 171 is formed in theattachment plate 169. Theopenings 170, 171 are adapted for receiving an attachment means therethrough, such as a screw, bolt, nail and the like, for securing thedevice 150 to a rafter or a joist. -
FIGS. 26 and 27 illustrate position of theconduit 11 in relation to thesupport device 150. As can be seen in the drawings, theconduit 11 rests within thechannel 156 and astrap 110 is wrapped around the exposed portion of theconduit 11. The strap is engaged with theopenings 161. - Construction regulations require that flexible or hard metal ducts be supported at defined intervals along their length and that sagging of the ducts between the supports not exceed more than 2½ inches. The present invention allows support of the air duct from the bottom without constricting the air flow, as is often the case with nylon straps, by allowing the flexible ducts or hard metal ducts to rest within the
main body - The
main body respective support members rivet channel main body support member main body support member support device - The projecting ends 15, 17 of the
main body 12 and ends 153, 155 of themain body 152 extend at a sufficient distance from the bottom of thechannels air duct 11 supported by thesupport device device - It will be understood that the particular shapes of the
main body support member main body 12 may be formed as a three-sided body forming a rectangular channel for accommodating an air duct or other conduit. Thesupport member 14 may have an I-shaped cross-section; it may be a solid rectangle, cylinder and the like. - Many other changes and modifications may be made in the design of the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.
